A student was sent home from school after he turned up for a breast cancer charity day wearing a pink MANKINI.

Staff had asked pupils to wear the bright colour as part of Breast Cancer Now's Wear it Pink campaign.

But the unnamed teen strolled into Lipson Co-operative Academy wearing nothing but the skimpy outfit made famous by Borat actor Sacha Baron Cohen.

Principal Steve Baker said the boy was "revealing too much" and told to go home to change.

He said: "We've done a series of assemblies on breast cancer awareness and we felt that it wasn't appropriate.

"He was revealing too much so he was told to go home.

"In terms of the seriousness of what we were trying to do, even though we aren't killjoys, the students still need to be aware of decency and respect and we felt it was less discreet than it should have been.

"These things occur regularly in schools but, as with all organisations, there are boundaries and we felt he had just crossed the boundaries.

"It's not a huge issue; it was just a mistake."

Despite the incident, Mr Baker said he was proud of his students who raised £1,000 for breast cancer awareness.
